Paper Abstract:
|
In this work we focus on function representation suitable for creating 3D freeform shapes with sketched silhouette
curves. We aim at comparison of two approaches for sketch-based modeling, namely the skeleton-based
convolution surfaces and variational implicit surfaces. Both methods are extended to handle smooth set theoretic
operations between components defined by sketching silhouette curves on different projection planes. Our
approach includes additional extensions to sketch-based systems like automatic skeleton generation that can be
directly used for object animation, carving operation, creating surfaces with handles and surface texturing. |
